How to Declare an Integer Array in Rust - Step by Step Examples
How to Declare an Integer Array in Rust ?
Answer
To declare an integer array in Rust, you can use array notation or the Vec container.
✐ Examples
1 Declare and Initialize an Integer Array
In this example,
- We declare an integer array named
numbers
with predefined values using array notation. - We print the array to demonstrate the initialization.
Rust Program
fn main() {
let numbers = [1, 2, 3, 4, 5];
println!("Integer Array: {:?}", numbers);
}
Output
Integer Array: [1, 2, 3, 4, 5]
2 Declare an Empty Integer Array
In this example,
- We declare an empty integer array named
empty_array
using the Vec container. - We print the array to demonstrate the declaration.
Rust Program
fn main() {
let empty_array: Vec<i32> = Vec::new();
println!("Empty Integer Array: {:?}", empty_array);
}
Output
Empty Integer Array: []

In this tutorial, we learned How to Declare an Integer Array in Rust language with well detailed examples.
